During the granting procedure of a patent several legal events are published by patent offices. Legal status information is highly relevant to determine, for example, if a patent is still in force, if opposition is filed, if the owner has changed etc. This presentation covers the different sources on STN providing legal status information, with a particular focus on INPADOC and EPFULL. STN provides sophisticated retrieval possibilities to search and monitor specific legal status events, and this session will include tips for setting up Alerts/SDIs and the effective searching for Supplementary Protection Certificates (SPCs).
